### Temperature

the measure of motion of matter particles.

### Fahrenheit scale

a temperature scale that defines the freezing point of water as 32 degrees and the boiling point of water a 212 degrees

### Celsius scale

a temperature scale that defines the freezing point of water as 0 degrees and the boiling point of water as 100 degrees

### Kelvin scale

the temperature scale in which the freezing point of water is 273 degrees and the boiling point is 373 degrees; 0 degrees is absolute zero

### Absolute zero

the temperature at which no thermal energy can be removed from matter.

### Heat

thermal energy that is transferred from matter at a higher temperature to matter at a lower temperature

### Conduction

the transfer of energy by direct contact. The term can apply to either heat transfer or electron transfer.

### Convection

the transfer of thermal energy by the circulation or movement of a liquid or gas

### Convection current

the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another

the transfer of energy by electromagnetic waves.

### Conductor

a material that transfers heat, electricity, or both easily.

### Insulator

a material that does not transfer, heat, electricity, or both easily.

### Thermal energy

the total energy of all the particles in an object.

### Specific heat

The amount of heat that must be absorbed or lost for 1 gram of a substance to change its temperature by 1°C.
